Sunix's USB4200V is a high-speed 480 Mbps USB 2.0 PCI card supporting the new USB 2.0 peripherals and all the existing USB 1.1 devices. The card adds four USB 2.0 high-speed ports to desktop system.

The card is an ideal choice for external storage devices, MP3 players, external writer, digital cameras, webcam, networking and video devices, and all other USB devices.
My comments:
This pdoduct does not hold up the promises it gives.
I have instelled this USB 2.0 card to my old PC system that runs Windows 2000 (the system originally had just USB 1.0 / 1.1 ports only). I bought the card to get 480 Mbit/s USB ports for fast external USB hard drive communications. And also for fast communications with USB memory "sticks".
The card does not hold the promises is has. The card was performing baddly with USB mass storage devices. It works worked somehow acceptably with USB memories (sometimes gives errors there as well) but failed to work with my brand new external USB hard disk (Lacie design by F.A.Porche with works nicely with other computers and the old slower USB port on my computer). Trying to use the card with Lacie drive causes problems, most of the times Windows does not detect the drive at all, if it detect it correctly what gets storaged to it is garbage, the USB communications crahes taking some times the whole Windows down...
Not good. I have tried the drivers that Windows autio detected for the card, drivers on the CD that came with the package, updated drivers from manufacturer web pages. When I downloaded the latest drivers the readme on that even said that the support for USB mass storage devices is limited (only bulk mode transfer supported if I remember right). So it seems based on this (if I understood right) that this card is indeed not good for the application it is recommended for and for what I bought it for.
So this card was for me pretty much waste of money... too late to return it to the shop (that shop I bought the card from is no longer operating).
Maybe I later try some other USB 2.0 card... but pretty possibly from some other manufacturer..
